Brass External Spur Gear With Spring Shaft

Featuring a golden-hued metallic disc with external straight teeth and an integrated spring-loaded shaft assembly, this component serves as a specialized transmission element for torque delivery and axial tensioning. The structure combines a precision-machined gear ring with a central through-bore that accommodates a stepped shaft and compression spring, typically used in mechanical locking mechanisms, clutch systems, or automated indexing devices where simultaneous rotation and return force are required.

Manufacturing focuses on maintaining strict concentricity between the outer tooth profile and the inner shaft bore to ensure smooth meshing and minimize radial runout during high-speed operation. The gear teeth require accurate control of module and pressure angle parameters, while the shaft assembly demands precise diameter tolerances to fit standard bearings or housing interfaces. The compression spring must provide consistent elastic force without interfering with the rotational freedom of the gear disc, requiring careful coordination of axial stack-up dimensions.

Leveraging CNC turning, hobbing, and grinding capabilities, production ensures high surface finish on the brass gear face and precise geometry on the steel shaft components. The facility utilizes数控插齿机 (CNC gear shaping machines) and数控滚齿机 (CNC hobbing machines) to achieve tight tooth profile accuracy, alongside precision lathes for shaft machining. Quality control involves verifying gear tooth thickness, pitch diameter, and shaft straightness using optical projectors and height gauges to meet ISO-grade fitting standards.

Customization supports various material combinations, such as brass or bronze for the gear body and alloy steel for the shaft, depending on load capacity and wear resistance needs. Surface treatments like passivation or black oxide can be applied to the steel shaft to enhance corrosion resistance, while the brass gear may undergo polishing for reduced friction. Lead times and costs vary based on the complexity of the spring specification, gear size, and required inspection depth, with flexible options for prototype validation and small-batch production runs.
